For Christmas I received a new graphics card for Christmas as well as a new PSU. I put in the PSU which is 600 watts it worked perfectly. I then proceeded to uninstall all of the drivers for the old AMD graphics card. Whenever I installed the New NVidia 660 GTX by Gigabyte it starts to boot gets to the BIOS or BOOT MENU screen and freezes. I cannot input anything and it refuses to work. I tried taking out the internal battery and it still doesn't work. I put the old graphics card back in so i could use the computer but since I don't have any drivers it won't work. If anyone had any ideas it would be appreciated. I cannot access BIOS either.

The computer is running an i5 with 16 gb ram. 2 tb hard drive. The old card is a radeon 7350 I think and the new power supply is an EVGA 600 watt PSU. If there is something wrong with the actual card what do you reccomend I do with it?

Make sure you have installed the graphics card into the first PCI Express 3.0 slot correctly and it's clicked into place. Then ensure to attached the 6-pin power connectors from the PSU to the top of your graphics card, which is required to power it (your PSU will need to support this - normally labelled as PCI-E cables). You might of missed this, in which case the motherboard will fail to power up the device and auto-shutdown for protection.

Connect the monitor cable only via the DVI-I connector (which carries both an analog and digital signal) if using an analog screen. Else you can use either DVI-D, DVI-I or HDMI, if working with digital.

Drivers don't matter, BIOS will use basic ones and Windows will install it's own standard native ones - if nothing better detected. It will still start, just with crumby and/or slow graphics (till you install the correct ones). It's either faulty hardware or your missing a connection somewhere.

If that isnt the same motherboard as what you have now, chances are you'll have to reinstall windows.

Also.. are you sure you put the right PSU power connector into the GPU? using the wrong connector can cause some problems.. Not to mention the wrong connector into the CPU 12v slot.

Another thing, its possible you hit the RAM sticks when you put the new GPU in, you can try reseating them to make sure they arent the problem as an issue with the RAM can cause such boot issues as well.

Its strange that even the old GPU wont boot up with the PC. even without GPU drivers installed the PC will still boot and then install the default graphic drivers once windows loads..-

If you ended up incorrectly putting the PSU connectors into the wrong places of the motherboard/GPU you could have damaged the motherboard. Again, putting the wrong connectors into the GPU could have buckled the PCI slot.

The GPU requires a 3.0 and my motherboard doesnt have a 3.0 connector and I tried the GPU on another computor and it works fine so I will have to upgrade my Motherboard. The old GPU now works thanks to some usb magic so thanks for all the help. Also is it a good motherboard?

And its possible. Just do a little troubleshooting first.Make sure the powersupply connectors are where they are supposed to be on the motherboard for the CPU, and make sure ur using the correct one for the GPU.

Reseating the RAM would be the next step. Carefully take them out of the DIMM slots and securely but gently place them back into the DIMM slots.With the PC OFF mind you

I just checked the cables and they are the correct ones to use seeing how the cpu used 1 4 pin connector and the gpu used a single 6 pin connector . The ram is set correctly and even though it was I reset it. The old gpu is now working but for some reason the new one still won't. I will try using the new card on a friends computer on the 28 and if it works there there is something wrong with mine and if it doesn't the card must be faulty. The card should work with his seeing as he is using the the 660 ti which is a bit higher than mine.
